Description

Nach dem Zylinderinnern sich öffnendes Brennstoffventil für Dieselmotoren. Das Brennstoffventil der Dieselmotoren besteht in seiner einfachsten Form bekanntlich in einer dünnen Spindel, die mitten durch den Zylinderkopf hindurchgeht und unten ventilartig ausgebildet ist, am anderen Ende aus dem Zylinderkopf herausragt und daselbst mittels Stopfbüchse dichtgehalten wird. Es ,vird in der Weise gesteuert, daß ein Steuerhebel auf den Spindelkopf einwirkt und so das Ventil öffnet, während eine Feder es schließen hilft, wenn der Steuerhebel zurücktritt.Fuel valve for diesel engines that opens after the inside of the cylinder. The fuel valve of diesel engines is known to exist in its simplest form in a thin spindle that goes right through the cylinder head and below is designed like a valve, protrudes from the cylinder head at the other end and there is kept tight by means of a stuffing box. It is controlled in such a way that a control lever acts on the spindle head and so opens the valve while a spring helps close it when the control lever steps back.

Es kommt aber nicht selten im Betriebe vor, daß die Stopfbüchse undicht wird und man sie nachziehen muß; dabei läuft man Gefahr, daß die Spindel steckenbleibt und der Betrieb dadurch gestört wird.However, it is not uncommon in the company that the stuffing box leaks and you have to tighten them; there is a risk that the spindle will get stuck and operation is disrupted as a result.

Zur Vermeidung dieses tlbelstandes hat man verschiedene Einrichtungen ersonnen, bei denen die Stopfbüchse in Fortfall kommt;. diese Einrichtungen sind aber entweder verwickelt und kostspielig oder weisen Mängel anderer Art auf.To avoid this bad situation there are various devices devised, in which the stuffing box comes to an end. these facilities are but either intricate and costly, or other deficiencies.

Nach vorliegender Erfindung ist ein auf das Brennstoffventil einwirkender Steuerstempel in einer verstellbaren Hülse geführt, die ihrerseits durch eine Stopfbüchse abgedichtet und mit Ventilsitz für ein an denn Steuerstempel vorgesehenes Ventil ausgebildet ist.According to the present invention is one acting on the fuel valve Control stamp guided in an adjustable sleeve, which in turn through a stuffing box sealed and with valve seat for one on then Tax stamp provided Valve is formed.

Auf der Zeichnung ist ein Ausführungsbeispiel in einem senkrechten Mittelschnitt argestellt.On the drawing is an embodiment in a vertical Middle section shown.

Das Speiseventil v, welches sich nach dem Zylinderinnern öffnet, wird im Ruhezustande durch die in einer geschlossenen Kammer gelagerte Schraubenfeder f geschlossen gehalten. Die Öffnung des Ventils v wird durch den nach außen ragenden, in der verstellbaren Hülse 1a genau geführten Stempels bewirkt, deren inneres Ende v1 ventilartig ausgebildet ist und im Ruhezustande auf dem inneren, als Ventilsitz ausgebildeten Ende der Hülse aufsitzt. Eine Stopfbüchse b dichtet die Hülse sicher ab, so daß im Ruhezustande die Kammer k nach außen völlig abgeschlossen ist und mir in den kurzen Perioden der Einströmung des Brennstoffes ein unbedeutender Verlust desselben stattfinden kann, während die Gefahr, daß die Ventilspindel steckenbleibt, gänzlich vermieden ist.The feed valve v, which opens after the cylinder interior, is at rest by the helical spring stored in a closed chamber f kept closed. The opening of the valve v is controlled by the outwardly protruding, in the adjustable sleeve 1 a precisely guided stamp causes the inner end v1 is designed like a valve and in the idle state on the inner, as a valve seat trained end of the sleeve is seated. A stuffing box b securely seals the sleeve from, so that in the state of rest the chamber k is completely closed to the outside and an insignificant loss to me in the short periods of fuel inflow the same can take place while the risk of the valve spindle getting stuck, is avoided entirely.

Diese Bedingung ist aber nur dann erfüllt, wenn die zwei Ventile v und v, so eingepaßt sind und verbleiben, däß sie gleichzeitig gut schließen. Da man sie von Zeit zu Zeit nachschleifen und allemal wieder genau einstellen muß, so muß diese Arbeit leicht ausführbar sein, sonst wird sie vom Maschinenführer vernachlässigt. Bei dem Erfindungsgegenstand kann nun die Hülse lz leicht von außen her mit geeignetem Schlüssel eingestellt werden, wenn ihre Stopfbüchse zuvor etwas gelockert worden ist, um die Drehung zu erleichtern. Zur Sicherung dagegen, daß die dauernden Schläge des Ventils die Hülse verstellen, ist ihre Krone mit einer feinen Verzahnung versehen, in die eine Sperrfeder a greift. Im allgemeinen wird aber dazu die Reibung der Stopfbüchse genügen.This condition is only fulfilled if the two valves v and v are fitted and remain so that they close well at the same time. Since it has to be regrinded from time to time and always precisely adjusted, this work must be easy to carry out, otherwise it will be neglected by the machine operator. In the subject matter of the invention, the sleeve lz can now be easily adjusted from the outside with a suitable key if its stuffing box has previously been loosened somewhat in order to facilitate the rotation. To ensure that the continuous blows of the valve adjust the sleeve, its crown is provided with a fine toothing into which a locking spring a engages. In general, however, the friction of the stuffing box will suffice for this.
